libselinux: move realpath helper to matchpathcon library

Instead of only doing path simplification and symlink following for the
matchpathcon helper instead do it in the library potion.  This was an
issue when in python some called selinux.matchpatchcon("//lib64", 0) and
got the wrong answer (because the // wasn't being dealt with)
